This site, comprising several protected areas, is situated predominantly along the Great Escarpment on Australia’s east coast. The outstanding geological features displayed around shield volcanic craters and the high number of rare and threatened rainforest species are of international significance for science and conservation.
With the opening of the Gwydir Highway in December 1960, the Gibraltar Range became accessible and moves were initiated to establish a national park. Approximately 14,000ha was reserved for public recreation by notification in the Government Gazette of 8 March 1963 and further 1,425ha was added by notification in the Government Gazette of 17 September 1965.
